Is there anyone with experience in photovoltaic integration from Wattsonic?
the manufacturer states in brochures only this “Integrated smart EMS
support various power applications”
LOXON state that it can integrate Wattsonic very effectively
Google also says nothing about the combination of wattsonic and HA
Hello,
I am also highly interested in this. I have an A-Tronix inverter [1] and think it probably is a relabeled Wattsonic gen2 distributed here in Germany. It would be nice to connect it to my Home Assistant. Is the Modbus interface provided at the EMS port via RS485?
yes, it looks like Wattsonic gen2.
look at table 3.43, that is the wiring, you need that two cables
I’m using this RS485 converter: https://www.aliexpress.com/item/1005003207091292.html
than check the loxone library, there is the register description. There are differences to gen3.
im new in this topic, so, is it possible to connect modbus to any type of inverter? is it possible to take disscusion in czech language somewere else? thank you very much…
I had this one and worked: RS485 TO POE ETH (B) - Waveshare Wiki
but I returned it, because my RPI4 is next to the inverter and I can use modbus RTU. And I hope that wattsonic will release new FW with modbus TCP.
Sorry for my late response. I had not enabled E-Mail notifications.
I have a different app “MixPower” and Website “https://www.st-ems.com”. But it looks quite similar to the screenshots of the Wattsonic app in the Play Store. I noticed that I can also use the Sunways (yet another brand) app and portal with my credentials. That was quite handy when st ems messed up their ssl certificate.
Hi all,
I’m having some troubles with my wattsonic gen3 inverter and I need “help” from those, who are reading registers over modbus and have wattsonic or clone(sunways, solinteg, A-Tronix, St-ems).
My issues:
when battery is full and exporting to grid, i’m getting BMS Warn Code=1, 2-5 times/day
sometimes I get Fault Flag3=64
sometimes Inverter Running Status changes to check and after 5 minutes returns to On grid. 5minutes is Czech requirement
sometimes after issue 2/3 I see error Bus Voltage Fault on inverter
sometimes I have power outage in house for 1-20ms, which restart modem/router/clocks, RPIs…this is the real issue
this is often related to points 2,4, but never 1. After power outage inverter always goes to check status, but that is ok.
all happens (except 1) very irregularly and rare:( sometimes 3x in 2 days and then 3-6days nothing
So could you, please, check your entity history if you see BMS Warn Code=1 or Inverter Running Status=check
thank you for help.
Fault Flag3 - address: 10116
Inverter Running Status - address 10105, value 1=check
BMS Warn Code - address: 33018
Nevedel som jak ti mam poslat sukromu spravu. Zijem v cechach a robim si aktualne fve . U nas vo firme predavame goodwe a sofar , ale kamos mi podnukol wattsonic. mám planovaný 15kw ale dá mi 20 za cenu 15 , co bude mat vyrazne lepsiu asimetriu, Som viacmenej movacik v HA (razbery PI , chytrý bojelr cez Shelly) ale pocitam s integráciou a automatiaciou FVE v HA …wattsonic ale nemá integraciu do HA …dokaze to tam bezny uzivatel dajak dostat ? a jak si spokojný s wattsonicom ?
